摘要 目的:动态监测降钙素原(PCT)水平,指导抗生素在慢性阻塞性肺疾病急性加重(AECOPD)患者的应用,减少不必要的抗生素暴露。方法将124例 AECOPD 患者随机分为两组,PCT 组66例,常规治疗组58例。PCT 组于入院当时即检测血清 PCT 水平,PCT 浓度≥0.25μg/ L 决定应用抗生素;PCT 浓度较前一次升高,判定所选抗生素不敏感,更换抗生素;PCT 浓度较前一次降低,判定所选抗生素治疗有效,抗生素应用不变;PCT 浓度﹤0.25μg/ L 决定停止应用抗生素。常规治疗组由医生根据临床经验结合患者胸片、症状、白细胞计数决定抗生素使用,主要观察指标为抗生素的使用天数、抗生素费用、住院时间。结果 PCT 组的抗生素应用天数多分布在7~11 d;而常规治疗组大部分在10~14 d 甚至更长,差异有统计学意义(P ﹤0.05)。两组抗生素费用比较差异有统计学意义(P ﹤0.05)。住院天数比较差异有统计学意义(P ﹤0.05)。结论 PCT 具有指导 AECOPD 抗菌治疗的作用,能够减少抗生素过度使用,减少住院天数。
